Former Midamar employees testify they were told by Aossey to mislabel productsThe trial, which started Tuesday, is expected to last a week

A U.S. Department of Agriculture inspector testified Wednesday that William Aossey, Jr. admitted to changing labels and stamps on halal beef products in order to ship them to Malaysia and Indonesia.

Jeff Griess, said Aossey knew the establishment number belonging to PM Beef in Windom, Minn., was changed on products to reflect a number belonging to J.F. O'Neill Packing Co. in Omaha, Neb., because O'Neill was only one of two or three beef suppliers who were approved to export halal beef to Malaysia and Indonesia during 2007-2010.

Griess also said Aossey signed a written statement saying he took full responsibility and admitted to telling employees to change the numbers and labels. Griess performed the Midamar inspection and found the illegal activity in February 2010.
